State of the art on the flammability of HFOs
An article recently published in the IJR reviews the flammability characteristics of 48 HFOs and blends for various experimental conditions.
A study assesses alternative mixtures to two pure hydrocarbon refrigerants
An article reviews more than 11,000 mixtures of refrigerants that could be interesting alternatives to pure R290 and R600a.
Latest news on the regulation of flammable refrigerants
Because many alternative low-GWP refrigerants are flammable, the evolution of the regulation governing these refrigerants is an issue that gives rise to many debates and initiatives.
US senators introduce bill to phase down HFCs
Thirty-two US Senators — 16 from each party — have cosponsored a bill to phase down HFCs and authorize EPA to facilitate transitions to next generation refrigerant technologies.
Cooling the world’s largest supercomputers
Direct liquid cooling is a highly energy-efficient solution for cooling supercomputers capable of performing millions or billions of billions of calculations per second. Here are two examples in the United States and France.
Publication of EU eco-design regulations for commercial refrigeration appliances
